> Let the user set the batch size for datanodes > # of slaves and don't show
> the warning. If they do, it just restarts all. Always recommend "1", and if
> greater than 1 is entered, show the new warning "Restarting more than one
> DataNode at a time is not recommended. Doing so can lead to data
> unavailability and/or possible loss of data being actively written to HFDS".
